Hyderabadi Biryani is a popular non-vegetarian variety of Biryani. It is a traditional celebration meal made using mutton(goat) or chicken and rice and is the staple of a die-hard Hyderabadi. The Hyderabadi Biryani is so named as it is seen mainly in the city of Hyderabad, India. The blending of Mughlai and Andhra cuisines in the kitchen of the Nizam (ruler of the historic Hyberabad state), resulted in a dish called the Hyderabad Biryani.The Dum Biryani is prepared with the Katchi Yakhni method (with raw gravy). The raw meat is marinated in curd, Indian herbs, spices and cooked only by the dum, or the baking process, which is done with rice. This is a challenging process as it requires meticulously measured time and heat to avoid overcooking or undercooking the meat.It is accompanied with Raita (a yogurt dish).There is also a vegetarian version of the Hyderabadi Biryani in which the place of the meat is taken by a mixture of vegetables such as carrots, peas, cauliflower and potato. The vegetarian version requires meticulously measured time and heat to avoid overcooking or undercooking.
